A Dominican national was hit with a six-year prison sentence in Boston for sneaking back into the U.S. and pushing the deadly drug fentanyl, federal authorities said.

Juan Carlos Santos-Ocasio, 44, also known as "Cristhian Aybar-Done," will face deportation for the second time after serving his term, this time carrying a weighty history of drug offenses around his neck like an albatross, having been previously convicted of heroin distribution conspiracy over a decade ago according to the U.S. Attorney's Office in Massachusetts. In 2010, after serving 37 months he was kicked out of the country but sneaky as a cat he found his way back into the States, where he picked up the old trades.

Following a guilty plea in October of last year for distribution and possession with intent to distribute the potent synthetic opioid, alongside his illegal reentry, Santos-Ocasio found himself once again at the mercy of the justice system. He will be subject to deportation upon the completion of his sentence, Justice Department stated, while detailing the charges and the proceedings that led to his sentencing by U.S. District Court Judge Leo T. Sorokin.

His latest arrest occurred in Lawrence, Mass., in November last year, where the authorities caught up with Santos-Ocasio and his illicit dealings involving more than 40 grams of fentanyl, a drug infamous for its role in the opioid epidemic sweeping the nation; the Acting U.S. Attorney Joshua S. Levy, Stephen Belleau from the DEA, among other officials, were the bearers of the announcement about this conviction, signaling yet another attempt to clean up the streets from dangerous substances and those who pedal them like fish in a market.

On record, Assistant U.S. Attorney Kaitlin Brown of the Worcester Branch Office brought the case against Santos-Ocasio to its close, ensuring this drug dealer's hiatus from society extends another six years, potentially saving countless lives from the grip of the devastating effects of fentanyl abuse in the process.
